Benefits of technology

[0007] The present invention also relates to a module for managing power in an electrical system of a vehicle. The module includes a first interface configured for coupling a first low voltage battery to a first high voltage battery. The module also includes a second interface configured for coupling a second high voltage battery to the first high voltage battery and to a plurality of high voltage loads. The module also includes a third interface configured for coupling a second low voltage battery to a plurality of low voltage loads. The module also inclu

Problems solved by technology

However, such known system has several disadvantages including that certain loads may remain connected to the battery when the switching mechanism is manipulated to the opened position.
Further, such known system is not readily adaptable to an electrical system of a vehicle having loads of multiple voltages.

Embodiment Construction

[0015] An energy management system 100 is shown in FIGS. 1A and 1B according to an exemplary embodiment. Energy management system 100 includes interfaces 122 and 124 for mechanical and electrical connection of a power source or battery system 20 to loads of an electrical system 30 of a vehicle. Energy management system 100 also includes a jump assistance system 130 having interfaces 132 and 134 for mechanical and electrical connection to an auxiliary power source 80 such as a battery. Auxiliary power source 80 provides for “jump assistance” or the jump-starting of the vehicle in the event that battery system 20 does not have sufficient charge to start the vehicle.

[0016] Energy management system 100 also provides “short circuit” (i.e. a low-resistance connection unintentionally established between two points in an electric circuit) protection of battery system 20. A short circuit could occur, for example, if a load (or loads) of electrical system 30 fail and such load draws a curren...

Abstract

A module for managing power in an electrical system of a vehicle is disclosed. The module includes a first interface configured for coupling to a first power source. The first power source is configured to power a plurality of loads of the electrical system. The module also includes a second interface configured for coupling to a second power source. The second power source is configured for charging the first power source. The module also includes a device configured for disconnecting the first power source from the plurality of loads. The device is also configured for disconnecting the second power source from the first power source.

Description

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS [0001] The following U.S. patent applications are hereby cross-referenced and incorporated by reference: U.S. Provisional Patent Application No. 60 / 318,512 titled “Energy Management System For Vehicle” filed Sep. 10, 2001.FIELD [0002] The present invention relates to an energy management system for a vehicle. The present invention more specifically relates to a module for managing the energy and power in the electrical system of a vehicle. BACKGROUND [0003] It is generally known to provide for a system for disconnecting a battery from a load of an electrical system of a vehicle. According to such known system, a controller manipulates a switching mechanism between a closed position and an opened position. In the closed position the switching mechanism connects the load to the battery, and in the opened position the switching mechanism disconnects the load from the battery. However, such known system has several disadvantages including t...
